Using Dwf toolkit, I read from a W2D file , getting all WT_Object , and use "serialize" function to write all WT_Object to a new W2D file.
I find the sizes of original file and the new file are different.
Then I compare WT_Object in original file and the new file and find some of WT_Object are of different data, especially WT_Polytriangle.
What's wrong with that?
